Abstract (en)

[origin: EP0838549A1] A press roll (2) intended, together with a press shoe (15), to cooperate with a counter roll (1) to form a press with long nip for paper or board machines, said press roll comprising two end walls (4, 5), a jacket (3), the edge portions (8, 9) of which are secured by an elastic clamping ring (24) to peripheral parts (6, 7) of the end walls, a form-stable clamping ring (25) being screwed to the inner side of the end-wall part (6, 7) to clamp the outwardly expandable elastic clamping ring (24) between itself and this so that the edge portion (8, 9) of the jacket (3) is clamped firmly against a counter-support member (27). According to the invention each end wall comprises guide means to provide a guided engagement relationship between the form-stable clamping ring (25) and the end-wall part. The guide means comprises one axially concentric guide groove (39) in the form-stable clamping ring (25) and an axial, concentric guide flange (43) in the end-wall part for cooperation with the guide groove (39), said guide groove defining radially externally a radial clamping surface (42) disposed opposite a corresponding clamping surface (47) of the end-wall part for cooperating clamping of the elastic clamping ring (24). <IMAGE>
